DIFFERENCE BETWEEN COMBED AND CARDED YARNS: Combing and carding are two ways to prepare the raw fiber for spinning. In order to make yarn, the raw fibers need to be fluffed up and aligned prior to spinning. -Carding creates a slightly fuzzier yarn as not as many of the fibers are aligned. -Combing creates a smoother yarn as the fibers are more aligned. Combing is the more expensive process as you have higher waste involved than with carding.
